A very nice system. How come you didn’t pick the Benchmark power amp?

Schiit Yggdrasil -- 21 bit?
Schiit says that Yggdrasil is a 21 bit DAC. But the DAC chips that they put in the device ( Analog Devices AD5791BRUZ, 2 per channel) are 20 bit with the error of plus-minus 0.5 LSB.
How can the DAC be 21 bit if the chips are 20 bit? Using two chips per channel does reduce the RMS voltage of the noise by a square root of 2. But how can you get to 21 bit from there?
Can someone please explain.

@defiantboomerang The speakers are active - 6 poweramps one for each transducer so I don’t need a power amp for this model. @mmeysarosh I believe ATC claim that a single ATC 300 cabinet will deliver an astonishing 121 dB SPL at less than .3% THD (with 10dB of headroom). The 300 cabinet is the same build as mine except for two 15" woofers per speaker instead of one (300 litre volume cabinet instead of 150 litre). So 117 dB SPL for one of my speakers at 1 meter sounds about right. ... please direct further questions on my system thread as I don’t think it appropriate to continue to discuss ATC speakers further on a thread that is specifically about Schiit’s excellent Yggdrasil DAC. I prefer not to hijack this thread. |
Ahh that would be Robert Harley of TAS, you can read here: http://www.theabsolutesound.com/articles/schiit-audio-yggdrasil-dac/ Build of a Yggi here https://www.youtube.com/watch?v=R3YZmaIRb6Q Video review here: https://www.youtube.com/watch?v=AFvUyK1oQRQ Really interesting discussion with Mike Moffat and Jason Stoddard: https://vimeo.com/194658219 I love the Yggi, its amazing for the price.

@shadorne The specification in itself is honestly rather vague, which is another gripe the entire industry as measurements must be standardized to permit consumers to compare. Far too many brands take liberties with specifications. Sure, it could be set out to lessen consumer confusion when providing only what is deemed necessary, but when a specification is incomplete such as the one listed on ATC's own website, its best to leave it out instead. |
